Notable outcomes were the significant drop in support for the Labour Party, who came third, and the UK Independence Party (UKIP) finishing second in a major election for the first time in its history, coming level with Labour in terms of seats but ahead of them in terms of votes. This was the first time in British electoral history that a party in government had been outpolled in a national election by a party with no representation in the House of Commons. The BNP also won two seats, its first ever in a nationwide election.[3] It also marked the first time the Scottish National Party (SNP) won the largest share of the European election vote in Scotland,[4] and it was the first time since 1918 Labour had failed to come first in a Welsh election.[5] It was the Democratic Unionist Party's (DUP) worst ever European election result, and also the first time an Irish Republican party, Sinn Féin, topped the poll in Northern Ireland.[6]

Turnout In Great Britain was 34.3%, with 15,137,202 votes out of a total electorate of 44,171,778.[7] Most of the results of the election were announced on Sunday 7 June, after similar elections were held in the other 26 member states of the European Union. Scotland declared its result on Monday 8 June, as counting in the Western Isles was delayed due to observance of the Sabbath.

Great Britain kept to the European wide trend towards the right.[3] The Labour Party, which was in its twelfth year as government of the United Kingdom, suffered a significant drop in support polling third, and UKIP finishing second in a major election for the first time in its history, coming level with Labour in terms of seats but ahead of them in terms of votes. This was the first time in British electoral history that a party in government had been out polled in a national election by a party with no representation in the House of Commons.

The Conservatives won in every region in Great Britain except the North East, where Labour won, and Scotland, where the SNP won.[7] Labour suffered most notably in Cornwall, where it came sixth behind Mebyon Kernow, and in the wider South West region and South East where it polled fifth behind the Green Party.[14] The BNP won two seats, their first ever in a national election. The share of the vote achieved by the English Democrats doubled.[15]

The turnout in Scotland was the lowest in the United Kingdom at 28.8%, with 1,104,512 votes out of a total electorate of 3,872,975.[7] In Scotland it was the first time the SNP won the largest share of the European election vote.[16] The SNP share of the vote rose by 9.4% points compared to 2004, this was the biggest positive swing for any party in any region in Great Britain.[7]

In Wales it was the first time since 1918 that Labour had failed to come first in a Welsh election, dropping 12.2%. In Wales, the Conservative Party topped the poll with the nationalist Plaid Cymru coming a close third. UKIP took the fourth Welsh seat, the first time Wales had elected a UKIP MEP.[17] Both the Liberal Democrat and the Green Party polled their lowest regional shares in Wales, though
Wales was the only region where the Liberal Democrat share of the vote rose compared with 2004.[7]

It was the DUP's worst ever European election result: the party had previously topped the poll in every European election in Northern Ireland since the first one in 1979.[6] It was also the first time an Irish Republican topped the poll with Bairbre de Brun of Sinn Féin coming first with 125,000 votes. The share of the votes for most parties in Northern Ireland remained essentially unchanged, the main exceptions were the DUP where their share of the vote fell by 13.8%, and the TUV, a party created by former DUP MEP Jim Allister whose share of the vote rose 13.7%.[7] The DUP's decreased vote share was largely blamed on the TUV splitting the vote.

During the 2005 Conservative Party leadership electionDavid Cameron argued for withdrawal of the Conservatives from EPP-ED and the formation of a new group. After the European election it was announced that the Conservatives were leaving the EPP-ED and forming a new group the European Conservatives and Reformists.[24] On 22 June 2009, the first official list of the new group's members was released.[25] On 24 June, the group held its inaugural meeting, in which Conservative MEP Timothy Kirkhope was named interim leader.[26] The first election for the group leadership was also scheduled for 14 July, pitting interim leader Kirkhope against fellow Briton Geoffrey Van Orden.[27] However, both Conservative leadership candidates were forced to forfeit the leadership in order to prevent it from falling apart, when then-Conservative MEP Edward McMillan-Scott defied his party whip and stood for one of the vice-presidency posts despite pledges the previous week that Polish MEP Michal Kaminski would be backed for it. Kaminski's bid for Vice-President of the European Parliament subsequently failed, and the Poles threatened to abandon the new caucus unless Kaminski was made the group leader in the parliament.[28]
